Peanut butter contains many nutrients that can improve heart health including:

  • Monounsaturated fatty acids (MUFAs)
  • Polyunsaturated fatty acids (PUFAs)
  • Magnesium
  • Niacin
  • Vitamin E

The proportion of unsaturated fats (PUFAs and MUFAs – “Healthy fats“) to saturated fats in the diet plays an important role in heart health. Peanut butter has a similar ratio to olive oil. Monounsaturated fat can help lower “bad” LDL cholesterol. 

Research suggests that including 46 g per day of peanuts or peanut butter into an American Diabetes Association (ADA) diet plan for 6 months could benefit the heart, improve blood lipid profiles, and control weight for people with diabetes. A high intake of nuts may have links to a reduced risk of mortality from heart disease or other causes.

Peanut butter is high in calories. So limit the intake if you don’t want to gain weight.

3. Good for Diabetes

Peanut butter is a relatively low carbohydrate food with good amounts of fats, protein and some fiber. Peanut butter with no added sugar doesn’t have a significant impact on blood glucose levels – good for diabetes.

Peanut butter is a good source of magnesium, which is an essential nutrient for people with diabetes. Continuous periods of high blood sugar may reduce magnesium levels in the body. Low magnesium levels are linked to pre-diabetes and type 2 diabetes.

Eating peanut butter from a young age may reduce the risk of benign breast disease (BBD). BBD increases the risk of breast cancer.

A study in the journal Breast Cancer Research and Treatment, reports that eating peanut butter and nuts at any age may result in a lower risk of developing BDD by age 30.

6. Good for Alzheimer’s and memory impairment

Niacin in foods helps prevent Alzheimer’s and other memory impairment conditions. One study shows how foods rich in niacin content reduced the chances of acquiring Alzheimer’s disease by up to 70%. Peanuts contain lots of niacin and vitamin E that actively fights off the early onset of Alzheimer’s.

More researches show that monounsaturated fats can directly affect our memories and cognitive functions. Olive oil and peanut butter contain lots of monounsaturated fats. These fats help maintain good mental health and function.

Nutritional facts of peanut butter

Good Protein Source

Peanut is actually a legume (beans, peas, and lentils) that happens to look and taste like a nut. Nutritionally, peanuts act like nuts, too. Although peanut butter is fairly protein-rich, legume protein is much lower in methionine and cysteine – compared to animal protein.

Peanut allergies

Peanut butter is good for you in general. However, peanut allergy has been increasing in children. Peanuts and other nuts are one of the 8 major allergens, with a peanut or tree nut allergy affecting over 3 million Americans, according to the National Institutes of Health (NIH).  It occurs by direct/cross-contact, and inhale. 

The NIH also notes that 20 % of those with an allergy will eventually outgrow and stop having reactions to nuts.


An allergic response to peanuts usually occurs within minutes after exposure. Peanut allergy signs and symptoms can include:

  • Digestive problems, such as diarrhea, stomach cramps, nausea or vomiting
  • Itching or tingling in or around the mouth and throat
  • Runny nose
  • Shortness of breath or wheezing
  • Skin reactions, such as hives, redness or swelling
  • Tightening of the throat

Anaphylaxis: A life-threatening reaction

Peanut allergy is the most common cause of food-induced anaphylaxis, a medical emergency that requires treatment with an epinephrine (adrenaline) injector (EpiPen, Auvi-Q) and a trip to the emergency room.

Anaphylaxis signs and symptoms can include:

  • Constriction of airways
  • Swelling of the throat that makes it difficult to breathe
  • A severe drop in blood pressure (shock)
  • Rapid pulse
  • Dizziness or loss of consciousness

A Potential Source of Aflatoxins

Peanut butter is quite nutritious, however, it may contain harmful substances like aflatoxins.

Peanuts grow underground, where they tend to be colonized by Aspergillus (ubiquitous mold). This mold is a source of aflatoxins, which are highly carcinogenic.

Some human studies have linked aflatoxin exposure to liver cancer, stunted growth in children and mental retardation. According to one source, the processing of peanuts into peanut butter reduces the levels of aflatoxins by 89%.

Essential peanut butter ingredients

Is peanut butter good for you? We love “PB”, but don’t know much about peanut butter. To be labeled peanut butter in the US, it must contain 90% peanuts. Roughly 540 peanuts are used to make one jar.

Peanut butter is a relatively unprocessed food: it’s just peanuts, often roasted, that are ground into a paste.

However, this doesn’t apply to many commercial peanut butters. Those peanut butter often contain various added ingredients: sugar, vegetable oils, and even trans fat to enhance the flavor. Eating too much added sugar and trans fat has created various health issues like heart disease. 

Peanut butter buying guide

Not all peanut butter is equal nor good for you. Which type of peanut butter is good for you? Know that there is no nutritional difference between smooth and crunchy peanut butter.

Here’s the definitive buying guide of peanut butter:

  • Skip brands with more than 3g of sugar
  • Avoid products that list hydrogenated oils
  • Skip the “no-stir” variety since it often signals added oils
  • Look for an “unsalted” version to reduce sodium


The healthiest kinds contain just peanuts and salt (but not too much). Check the ingredient labels before you buy them.

Natural and conventional peanut butter

Both have almost the same nutritional values. Natural peanut butter is not necessarily healthier than conventional, except that it most definitely doesn’t contain ingredients like hydrogenated vegetable oils (unhealthy fats), corn maltodextrin, and mono-and di-glycerides. Avoid those ingredients.

Natural peanut butter may need a little more stirring without the added emulsifiers and may have a bit of a shorter shelf life than ones with hydrogenated oil. Store them in a dark, cool cabinet or the fridge to make them last longer.

“Reduced/low fat” peanut butter

Surprisingly, this isn’t an easy answer. They often contain the same amount of calories and more added sugar than normal versions. Most low-fat ones make up for the cut back on nutrients by adding in sugar and partially hydrogenated oils, or trans fats, which are not good for your health.

Flavored peanut butter

With recent growing popularity, we start seeing different blends like coconut and sunflower seeds, or flavored ones like peanut butter and banana. Check the labels to make sure not to contain extra salts, sugars, or preservatives for your healthiest choice.

Remember: those added flavor ones almost always contain added sugar, carbohydrates, and other shelf-stabilizing agents. So avoid those!

How to make peanut butter at home
